OVERWEIGHT-REGISTER.

SPECIFICATION forming part of Letters Patent No. 723,733, dated March24, 1903.

Application filed October 2, 1902. fierial N0.125,'706. (N model.)

To all whom it may concern:

Be it known that I, JOHN ROLLER, a citizen of the United States,residing at Manchester, in the county of VVashtenaw and State ofMichigan, have invented certain new and use- .ful Improvements inOverweight-Registers;

The object of the invention is to providea device of this characterwhich may be applied for use in connection with any ordinary beam-scaleand which is simple of construe tion, efficient in use, and adapted tobe manufactured at a low cost.

With this and other objects in View the inv vention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described, and

particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a View showing the applicationof the invention for cooperation with the weight-beam of a scale. Fig. 2is a face viewv of the device detached. Fig. 3 is a perspective view ofthe gearing. Fig. 4 is a face view of the rotating dials.

Referring now more particularly to the drawings, 1 represents theweight-beam of anordinary pair of scales, and 2 the guide for the freeend of said beam.

3 denotes the register attachment, which comprises a suitable casing 4,provided with a bracket 5 for fastening it the guide 2 above thefree'end of the beam 1. The face of this casing is formed of a dial 6,provided with a circular row of numerals from 1 to 16, inclusive,designating the ounce-divisions of a pound and apertured to exposeinterior pound and ounce dials 7 and 8. 00-

operating with the dial 6 isa hand or pointer 9, mounted rigidly uponthe front end of a shaft 10, journaled in the front and rear walls ofthe casing. This shaft carries a fixed pinion 11, which meshes with thetoothed portion of a vertically-movable rack-bar 12, provided at itslower end with a head 13, adapted to be engaged by the beam 1. Theupward movement of this rack-bar imparts motion in a direction to movethe hand 9 a greater or less distance around the dial 6 and is opposedby a coiled spring 14,,surrounding the rack-bar between a collar thereonand an adjusting-nut 16, mounted on the casing 4:. When the beam 1 movesdownward and out of contact with the head 13, the spring 14 restores therack-bar to its normal position. By means of the nut-16 the spring maybe adjusted to regulate the movement of the rack-bar, as occasionrequires. The shaft 10 has also fixed thereto a ratchet-wheel 16,engaged bya pawl 17 on a gear-wheel 18, loose on said shaft. wheelengage. the pawl and rotate the gearwheel when the shaft is turned inone direction by the upward movement of the rackbar, but ride over thepawl to prevent move- 'ment of said wheel when the shaft turns ingearwheel 19, fixed on a shaft 20, carrying the ounce-dial 7 and turnedby the movement of said gear-wheel 18 to rotate said dial. Thisgear-wheel 19 is provided with a tooth or projection 20 to operate agear-wheel 21, fixed on a shaft 22, carrying the pound-dial 8. On eachcomplete revolution of the gear 19 the t0oth-20 engages and turns thegear 21 a distance sufficient to bring one of the numerals on the dial 8into view at the opening therefor in the. dial 6.

Of course it will be understood that the The teeth of this ratchet dials7and 8 may be stationary and the shafts greater or less degree ofrotation is imparted to shaft 10, which through the medium of the pawland ratchet and gear 18 will transmit motion to the gear 19 andshaft 20,by means of which the dial 7and hand 9 will be simultaneously actuatedto indicate the overweight in ounces, the one for permanentorprogressive'indication and the other for temporary indication or inspection.Thus as the beam vibrates to a greater or-less extent the amount of theoverweight in ounces will be registered at the front of the casing 4.Upon the down movement of the beam and the release of the same fromengagement with the head 13 the spring14 will force the rack-bar 12 backto its normal position and reset the device for further operation. Whenthe gear 19 has made almost a complete revolution indicating fifteenounces overweight, a further up ward movement of the rack-bar 12 willtransmit motion thereto to bring the tooth 25 into engagement with oneof the teeth of gear 21, thereby turning the dial to expose the numeral1 thereon, indicating a total overweight register of one pound, and ifduring this movement the overweight of material in the scale-pan shouldbe more than one ounce a further rotation of the gear 19 would beproduced and 'cause the numeral, 1 on the dial 7 to be exposed, thusindicating that during a prescribed time one pound and one ounce ofmaterial has been lost by overweight. It will therefore be seen thatthe'device not onlyindicates the overweight at each weighing operation,but'registers the total overweights, so that the total amount of goodsor materials lost during the course of a day may be readily ascertained.

From the foregoing description, taken iii connection with theaccompanying drawings, the construction and operation. of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention. 7 n 7 'Having thusdescribed my invention, what I claim as new, and desire to secure byLetters Patent, is r o 1. An overweight-registering attachment forscales, comprising a casing, indicating means, a train of gearing foroperating said indicating means, a rack-bar adapted to be operated bythescale-beam to transmit mo tion to said gearing, a spring forretracting the bar, and means for regulating the resistance of saidspring, substantially as set forth.

2; An overweight-registering attachment for scales, comprising a casing,indicating means, a train of gearing for operating said indicatingmeans, said gearing including an operating-shaft and an operating-gearloose thereon, a pawl and ratchet for turning the gear when the shaftturns in one direction, and a rack-bar engaging a pinion on the shafttoturn the same, substantially as shown and described. 7 7 V Intestimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. r a
